large scale hosts failure

Registered by suzhengwei

According to the workload, some instances may have a low value, while other instances have a high value to the operator or users.

When large scale hosts failed in the same time, the reouses is decreasing. What's worse, there is not enough resources to recovery all the instances.

We should make sure the instances recovery in order, while instances with high value should recovery at first. We also need to bring some mechanism, in case that the cloud platform chaotically recovery and lost stability.
